Machine learning finds new metamaterial designs for energy harvesting

Posted by in categories: chemistry, robotics/AI, sustainability

Electrical engineers at Duke University have harnessed the power of machine learning to design dielectric (non-metal) metamaterials that absorb and emit specific frequencies of terahertz radiation. The design technique changed what could have been more than 2000 years of calculation into 23 hours, clearing the way for the design of new, sustainable types of thermal energy harvesters and lighting.

The study was published online on September 16 in the journal Optics Express.

Metamaterials are synthetic materials composed of many individual engineered features, which together produce properties not found in nature through their structure rather than their chemistry. In this case, the terahertz metamaterial is built up from a two-by-two grid of silicon cylinders resembling a short, square Lego.

Researchers’ new method enables identifying a person through walls from candidate video footage, using only WiFi

Posted by in categories: habitats, internet, law enforcement, security, surveillance

Researchers in the lab of UC Santa Barbara professor Yasamin Mostofi have enabled, for the first time, determining whether the person behind a wall is the same individual who appears in given video footage, using only a pair of WiFi transceivers outside.

This novel video-WiFi cross-modal gait-based person identification system, which they refer to as XModal-ID (pronounced Cross-Modal-ID), could have a variety of applications, from surveillance and security to smart homes. For instance, consider a scenario in which law enforcement has a of a robbery. They suspect that the robber is hiding inside a house. Can a pair of WiFi transceivers outside the house determine if the person inside the house is the same as the one in the robbery video? Questions such as this have motivated this new technology.

SETI Scientist: Aliens May Have Left a Spy Probe Orbiting the Sun

Posted by in categories: alien life, satellites

O.o I remember one time seeing an article I was not sure of basically talking about aliens coming out of the sun I thought it was crazy at the time but now I am not so sure o, o.


New research argues that ancient aliens could have turned space rocks orbiting near Earth into de-facto spy satellites.

Tesla patents new liquid-cooled charging connector

Posted by in categories: sustainability, transportation

Tesla has filed for a new patent on a design for a liquid-cooled charging connector, like the one used at its Supercharger stations.

With the advent of faster-charging electric vehicles, charging station manufacturers need to develop higher-powered DC fast charger and those machines generate more heat that needs to be dissipated.

Boston Dynamics Begins Selling ‘Spot’ Robot

Posted by in category: robotics/AI

For years, Boston Dynamics’ only commercial product has been vaguely unsettling videos of robots moving in realistic ways. That changes today. No, the robots aren’t getting less creepy. Boston Dynamics has a real commercial product: Spot. This quadrupedal robot is shipping out to select companies, but it could expand to general sales eventually.

We’ve seen Spot (originally known as SpotMini) show up in various video demonstrations. You’ve seen it twerk, and now you might see it work. Boston Dynamics isn’t entirely certain what sort of work Spot will do, but that’s why it’s starting with a limited sales program. It wants to work closely with early adopters to evaluate Spot’s usefulness in the real world.

‘Revolution’ in prostate cancer care as off-label breast cancer drug doubles survival

Posted by in categories: biotech/medical, genetics

A breast cancer drug has been used to double the survival of men with advanced prostate cancer, becoming the first successful precision medicine for the disease.

Doctors at the Royal Marsden Hospital who conducted the trial say the results amount to a “revolution” in prostate cancer care.

They conducted genetic testing on more than 4,400 patients to identify those with one or more of 15 types of DNA fault.

New aluminum batteries for renewables storage

Posted by in categories: energy, materials

The devices, developed by a European research team, are said to have twice the energy density of conventional aluminum devices. The scientists used a cathode made of anthraquinone, instead of one based on graphene, increasing energy density.
